The country was difficult, consisting of rude mountain tracks, with dense and impenetrable jungle between. One peculiarity of this jungle was its being infested with leeches, which “penetrate loosely-woven cloths, and deprive the wearer of a good deal of blood before he finds them out. They get far up the noses of horses, goats, etc., and cannot be removed without subjecting the poor animal to a couple of days without water, which being afterwards offered to him, the leeches also want to drink, and may be seized. If allowed to remain, the animal becomes a mere skeleton.” The order of march, too, was peculiar in such a terrain. Flanking patrols were impossible, and the column was therefore protected by small bodies halted in succession, which in due course joined the rear of the column as fresh bodies in advance took their place. The defence was not serious: there was some desultory jungle fighting, with little loss on either side; there were stockades and stone breastworks constructed, but not seriously held or for long; there were huge masses of stone, “booby traps,” so arranged on a bamboo platform that a few cuts with a knife would release them to roll down the mountain side, but no loss was effected by them. Finally, the country was pacified and war ceased; but a second expedition, in which the Derbyshire Regiment took part, was necessary in 1888, where the same difficulties were encountered and surmounted, and a small engagement took place at Gnatong. The small Umbeylah, or Ambela, campaign, as it spelt in the official history, was somewhat more serious. There had been fanatical outbreaks by Hindustanis in the district beyond the territory of the Buner Khels, lying opposite the Hazara district of the Indus valley, and bordering on the area ruled by the Akhund of Swat. This personage was a spiritual as well as a temporal ruler, and combined theological distinction with political power. The force was organised in two columns. That in the Hazara district had the 51st and 93rd Regiments, with the native troops, and was intended to watch the frontier at first defensively. The other had at first the 71st Highland Light Infantry and the 101st Royal Bengal Fusiliers to stiffen the Indian regiments, and to these were added later the 79th and 7th Royal Fusiliers, with the 7th Hussars.
